808cuda, I tried Summit and had no luck searching for LED's. Would you have a part number?




I used these when I did my Dart. Two years later they are still working. If you do a search on Summit using "warning lights" all sorts of stuff comes up.

RDJ, I tried that, all kinds of choices. But nothing "in dash" which is what I need. Is there a "holder" that would allow it to clip in to the panel?

In my Dart, I made a custom panel with all aftermarket gauges. One of the wires on the LED gets wired into the factory blinker (brights, etc) and the other runs to ground. If the holes for the LEDs are the proper size, it fits right in and the wires are behind the panel where you can tap into the factory wires.

I don't know how far you want to go with this, but if you drilled out the current blinker with the proper size hole (or a hole somewhere else), put the LED in the hole and wired into the factory wires it would work.

Hey Dart67,

RDJ beat me to the punch! I used the smaller 1/8" LED's. Just drill a hole and press fit them in place. No resistor needed too, real nice.

Greatly appreciate the help! Soon as the rest of the gauges come in, I plan to start drilling holes in the new insert.

Does anybody have pics of the process of laying out the new wires behind their insert? I'm leaning toward putting in the new harness while everthing is apart......

The LED is the current limiting device in the circuit, the resistor will not create a fire hazard.
I use LED's for that purpose without resistors.
Are they 12 volt and the resistor is there to protect against 15v?



Actually, the RESISTOR is the current limiting device, not the LED. If there is no resistor (whether built-in to the LED or in series) and you put 12 volts across the LED with the proper polarity, it will be immediately rendered useless due to excessive current. If you're familiar with electronics and the associated math, then you know the PIE calculations....


I may not appear to be doing much, but on the cellular level I'm really quite busy!

The round plug that plugs into the back of your panel has the wires you need to tap into. For a 73 Dart, they are:

Parking brake warning light - Black
Oil warning light - grey
fuel sender - dark blue
highbeam indicator light - red
rt turn indicator - tan
lft turn indicator - light green
temp gauge - green
dash lights - orange

Yours are probably different, check a wiring diagram for your car. If all you are doing is replacing the signal and brights indicators, just tap into the factory wires with one wire on the LEDs and run a ground to a barrier strip with 18 or 16 gauge wire. Get a barrier strip bridge/jumper (the barrier strip and jumper is available at Radio Shack), and then you can run one 10 or 12 gauge ground wire from the barrier strip to a steering column bolt. The barrier strips take a certain size u -shape-connector, but I bought 64 on ebay for like 5 bucks or something.

One comment, The parking brake warning light doesn't work, but all the rest do.

Unfortunately, all my pictures of my project were on a hard drive that fried. Take note all, put your important pics on a CD, hard drives will fail eventually.

BTW, here is a pic of my gauge panel for the Dart before it was installed

Ypur insert looks great RDJ! What are the two small LED's beneath the gauge used for?

The red LED is for the oil pressure, but I have an oil pressure gauge, so it is not hooked up. Eventually I will put a tee at the sender and have a sensor for the light.

The amber LED is for the parking brake warning, but the light never worked, and I didn't try very hard to figure out why. All the rest of gauges and lights have been working fine for the last two years. I put those red transparent covers for the dash lights, and it looks pretty cool at night.

The stock headlight switch and wiper switch were used in the setup, so I didn't have to hack at those wires or stock plugs (except to lengthen the wires for the wiper switch).
